The Zombies video slot is a 20-payline game produced by NetEnt software featuring two wilds in reel play and some interesting features to boot.
The symbol helpfully marked “Wild” appears on all reels except 3 and acts just as a typical wild, substituting for other symbols to make up winning combinations. In reel 3 is a stacked wild – represented, naturally, by a zombie. Reel 3 is also subject to helpful nudges that the player may employ to make wins.
The “Random Wild Feature” is also random in appearance and can be launched after any spin (except those entering another feature). Up to six symbols may be made wild within this feature.
The scatter symbol is the “virus container.” Three or more of these will win five free spins, and each free spin is preceded by a brief bonus round in which the player shoots down zombies for extra credits. A bonus multiplier increases payouts gradually from 1x to 10x through the free spins.
